Cation Exchange Capacity
–CATION-EXCHANGE CAPACITY OF SOILS (By METHOD 9081)
The soil sample is mixed with an excess of sodium acetate solution, resulting in an exchange of the added sodium cations for the matrix cations. Subsequently, the sample is washed with isopropyl alcohol. An ammonium acetate solution is then added, which replaces the adsorbed sodium with ammonium. The concentration of displaced sodium is then determined by atomic absorption, emission spectroscopy, or an equivalent means.
|Sample Volume||8 oz|
|Sodium milliequivalents||Na meq|
